On the 11th hour of the 11th day of the 11th month of 1918, an armistice, or temporary cessation of hostilities, was declared between the Allied nations and Germany in the First World War, then known as "the Great War." Commemorated as Armistice Day beginning the following year, November 11th became a legal federal holiday in the United States in 1938. In the aftermath of World War II and the Korean War, Armistice Day became Veterans Day, a holiday dedicated to American veterans of all wars.

Veterans Day originated as "Armistice Day" on Nov. 11, 1919, the first anniversary of the end of World War I. Congress passed a resolution in 1926 for an annual observance, and Nov. 11 became a national holiday beginning in 1938. Veterans Day is not to be confused with Memorial Day--a common misunderstanding, according to the U.S. Department of Veterans Affairs. Memorial Day (the fourth Monday in May) honors American service members who died in service to their country or as a result of injuries incurred during battle, while Veterans Day pays tribute to all American veterans--living or dead--but especially gives thanks to living veterans who served their country honorably during war or peacetime
